Digital Proximity and Ambient Light Sensor
Preliminary Datasheet
Description
The APDS-9900/9901 provides digital ambient light sensing (ALS), IR LED and a complete proximity detection system in a single 8 pin package. The proximity function offers plug and play detection to 100mm (without front glass) thus eliminating the need for factory calibration of the end equipment or subassembly. The proximity detection feature operates well from bright sunlight to dark rooms. The wide dynamic range also allows for operation in short distance detection behind dark glass such as a cell phone. In addition, an internal state machine provides the ability to put the device into a low power mode in between ALS and proximity measurements providing very low average power consumption. Th
